Working with Load Balancer Timeouts
If session-stickiness is configured with a timeout on the Load Balancer, that timeout value must be higher than the PeopleSoft Inactivity Logout timeout configured in the current Web Profile.
Keep in mind the session cookie name format. The session-cookie name must not start with a digit (0-9) and must not contain dots.
Example of bad name for session-cookie: 11.12.13.14-80-PORTAL-JSESSIONID
Example of good name for session-cookie: FINTSTWEB-80-PORTAL-JSESSIONID
